The NetBackup Media Server Encryption Option provides tape device drivers that fit between the NetBackup master server and the client media servers. These drivers are installed on each media sever in the NetBackup configuration. When NetBackup sends a read or write request to or from the storage medium, the request is intercepted by the MSEO virtual tape device and evaluated by a MSEO Security Server. If the request successfully passes evaluation, the request and protected data are passed to the real tape device.
